No glitches, one very minor quirk and a whole lot of trickery and misdirection. What weird way will work?

Also, don't jump at the start, or the chomper will move and destroy itself and a certain very useful barrel. Let the chomper out first.

(The working title of this level was first "Bending Logic" and then "Mildly Sane". The sign has a reference to the second one.)
EDIT: Marinus has found a way to save a wooden box by being crafty. However, I'm fearing that this one trick will make all sorts of unintended puzzle solutions pop out, so I had to squander it quickly. The result is a little less misdirection, but whatever, it's still a hard level. Please download the revised "B" version -- if you have been playing the intended way then the solution is exactly the same. The old version is there for historical purposes.
EDIT 2: Amnon has told me that the "B" version is even more broken, so here is the "C" version instead.
